Does anyone have any idea where I could buy the "official" tool that Audi dealers use to clean the sunroof drains? I saw it, it is flexible plastic tube with a metal weight at the end. I have persistent issues, so I want one to DIY often. I want to use the "official" tool bc I don't want to make it worse. My crappy local dealership won't help. I have an 07 A8L. Thanks.

 

I do not know of any specific tool for sunroof drains. Use a piano wire , old speedo cable or carefully use some compressed air.
Also it is best to keep the sunroof closed when not in use , don't park under trees to prevent organic debris from collecting.

 

I also do not know of any specific tool for sunroof drains, you can search it on the internet
